A Bold Challenge from the Zero Day Initiative
In an unprecedented move, the Zero Day Initiative (ZDI) is offering a jaw-dropping \$1 million reward for anyone who can crack into WhatsApp using a zero-click exploit—no user interaction required. This challenge is part of the highly anticipated Pwn2Own Ireland 2025 cybersecurity contest, scheduled to take place in Cork, Ireland, from October 21 to 24. The event is co-sponsored by Meta, along with Synology and QNAP, signaling a clear focus on high-stakes mobile and messaging vulnerabilities.
This year’s competition shines a spotlight on zero-click attacks, a type of vulnerability that enables hackers to remotely execute code on a device without the user having to click, tap, or even open a message. It’s a rare and dangerous exploit, especially given WhatsApp’s massive user base exceeding three billion people globally. The million-dollar incentive is ZDI’s way of drawing out the world’s most elite hackers and ethical researchers to help expose critical flaws before bad actors do.
In addition to WhatsApp, the event will span eight categories including mobile phones, messaging apps, smart home devices, wearable tech, home networking systems, surveillance equipment, and more. Meta’s Ray-Ban Smart Glasses and Quest 3/3S headsets, along with the Samsung Galaxy S25, Google Pixel 9, and Apple iPhone 16, will also be part of the challenge set.
For mobile devices, ZDI has expanded the scope of acceptable attack methods. Competitors can now exploit vulnerabilities via USB ports, even on locked phones, in addition to traditional wireless vectors like Wi-Fi, Bluetooth, and NFC (Near Field Communication). This introduces new complexity and real-world relevance to the competition.
Registration is open until October 16 at 5 p.m. IST, and contestant order will be decided by a random drawing. Once vulnerabilities are successfully demonstrated, vendors are given 90 days to patch the flaws before ZDI publicly discloses them.
Last year’s Pwn2Own Ireland event paid out over \$1 million in prizes for more than 70 unique zero-day vulnerabilities, with Viettel Cyber Security alone taking home \$205,000 for exploits across several major platforms. The stakes are even higher this year, especially with Meta’s unprecedented investment in finding potential zero-day threats in its widely-used messaging platform.
Meanwhile, ZDI has hinted that the Messaging App Exploits category was introduced last year, but no participants attempted it—likely due to the difficulty involved. The \$1 million prize may just be the right spark to change that.
What Undercode Say:
The Rising Stakes in Offensive Security Research
The dramatic \$1 million bounty for a WhatsApp zero-click exploit isn’t just headline fodder—it’s a loud signal that vulnerabilities in communication platforms have become one of the most valuable targets in cybersecurity. Zero-click flaws are among the most dangerous and difficult to detect, often leaving victims compromised without any trace of malicious activity. Meta’s decision to fund this initiative underscores the corporate urgency to preempt advanced persistent threats (APTs) that increasingly rely on silent infiltration methods.
Zero-Click Attacks: The Holy Grail of Exploits
Zero-click attacks bypass all conventional security layers. There’s no malicious link to avoid, no suspicious attachment to detect. This class of exploit has historically been used in nation-state cyber-espionage, with examples like Pegasus spyware showing how powerful and invisible these techniques can be. The million-dollar reward is proportional to the risk these exploits pose and the technical complexity required to uncover them.
Why WhatsApp?
With more than 3 billion users, WhatsApp is one of the most attacked communication platforms globally. Its end-to-end encryption and popularity among both everyday users and enterprise customers make it a prime target. The fact that ZDI and Meta are willing to pay seven figures to uncover vulnerabilities hints at existing concerns about WhatsApp’s underlying architecture, particularly in how it processes messages, attachments, and calls.
Expanded Attack Vectors = Greater Realism
The inclusion of USB-based attack methods on locked devices reflects a shift toward more real-world threat modeling. Attackers in the wild often rely on physical access vectors—especially when targeting high-value individuals. By allowing such methods, ZDI ensures the vulnerabilities discovered aren’t just academic, but tactically relevant in modern threat environments.
Meta’s Public Relations Play
Meta’s involvement serves a dual purpose: security hardening and brand reputation management. By openly backing bug bounty events, the tech giant presents itself as proactive and transparent, which is crucial after years of controversies surrounding data privacy, misinformation, and surveillance. Pwn2Own gives Meta a controlled environment to learn about potential flaws before cybercriminals do.
Previous Success Shows What’s at Stake

The Strategy Behind Zero Day Disclosure Timelines
ZDI’s policy of giving vendors 90 days to fix a flaw before public disclosure is a balance between responsible reporting and public accountability. It ensures companies act quickly while giving users a heads-up if vulnerabilities aren’t addressed in time. In an age where software patches often lag behind exploits, this structure offers a fair pressure mechanism.
The Untapped Potential of Messaging App Exploits
It’s telling that the messaging app category was ignored last year, likely because zero-click vulnerabilities are extremely hard to identify without access to proprietary codebases or insider knowledge. Now that a two-comma reward is up for grabs, expect participation from nation-state-level researchers, security firms, and dark web veterans hoping to transition into white-hat notoriety.
🔍 Fact Checker Results:
✅ Yes — A \$1M reward has been confirmed by ZDI for a WhatsApp zero-click exploit
✅ Yes — The contest will be held in Ireland, co-sponsored by Meta, Synology, and QNAP
✅ Yes — Registration deadline is October 16, with the event running from Oct 21-24 in Cork
📊 Prediction:
With the astronomical prize and Meta’s backing, 2025 is likely to be the year someone finally cracks WhatsApp’s zero-click defenses. Given last year’s silence in the messaging category, this bold financial move will almost certainly draw world-class talent who may already have exploits in hand. Expect record-breaking vulnerabilities to be revealed—ones that could reshape how messaging apps are secured in the future.
